Weird argument. Given they're in the US, not complying with US sanctions on Iran isn't an option either.
That’s not how sanctions work. A company can’t knowingly service a customer under sanctions. If your account was termination for sanction related reasons, they have no choice but to shut it down as fast as possible once they know that fact.
They cannot continue to service it for a few days or even service transfer requests. It’s a hard stop.
No, I don't think so.
